| Term | Definition |
|---|---|
| Algebra | A mathematical language of symbols including variables. |
| Algebraic expression | A combination of variables numbers and at least one operation. |
| Associative property | The way in which numbers are grouped does not change the sum or product. |
| Base | In a power, the number used used as a factor. In 10 3 the base is 10 that is 10 3 =10*10*10. |
| Coefficient | The numerical factor of a term that contains a variable |
| Commutative property | The order in which numbers are added or multiplied does not change the sum or product. |
| Constant | A term without a variable. |
| Defining the variable | Choosing a variable and deciding what the variable represents. |
| Distributive property | |
| Equivalent expressions | |
| Evaluate | |
| Exponent | |
| Factoring the expression | |
| Greatest common factor | |
| Identity property | |
| Least common multiple | |
| Like terms | |
| Numerical expression | |
| Order of operations | |
| Power | |
| Simplest form | |

| Variable | |
| To multiply a sum by a number, multiply each addend by the number outside the parenthesis. | |
| Expressions that have the same value regardless of the values of the variables. | |
| To find the value of an algebraic expression by replacing variables with numbers. | |
| In a power, the number that tells how many times the base is used as a factor. 5 3 the exponent is 3. That is, 5 3 =5x5x5. | |
| The process of writing numeric or algebraic expressions as a product of there factors. | |
| The greatest of the common factors of two or more numbers. | |

| The process of writing numeric or algebraic expressions as a product of there factors. | |
| The greatest of the common factors of two or more numbers. | |
| Properties that state that the sum of any number and 0 equals the number and that the product of any number and 1 equals the number. | |
| The smallest whole number greater tha zero that is a common multiple of each of two or more numbers. | |
| Terms that contain the same variables to the same power. | |
| A combination of numbers and operations. | |
| The rules that tell which operation to perform first when more than one oppration is used. | |
| A number expressed using an exponent. The power 3 2 is read three to the second or three squared. | |
| The status of an expression when it has no like terms and no parenthesis. | |
| Each part of an algebraic expression separated by a plus or minus sign. | |
| A symbol usually a letter used to represent a number. |
